SPECIFICATION formingpart of Letters Patent No. 682,114, dated September 3, 1901.

Application filed October 20, 1900- To all whom, it may concern-.-

Be it known that I, HENRY T. PAISTE, a citizen of the United States, residing in Phila delphia, Pennsylvania, have invented certain Improvements in Rosettes, of which the following is a specification.

My invention relates to certain improvements in that class of electrical fixtu res known as rosettes, and has for its object the provision of means which shall prevent the two said rosette is subjected to vibration. This object I attain as hereinafter set forth, reference being had to the accompanying drawings, in which- Figure 1 is a detached perspective View of the two halves of the rosette to which my invention is applied; and Fig. 2 is a cross-secthereof, showing the detail structure of m'y improvement.

One of the objections to rosettes of the forms at present manufactured has been that whenever they were used in places in which there was any vibration the lower half would sooner or later work loose and finally become detached from the fixed half. As it will be understood by those familiar with the construction of these fixtures, this is but the natural consequence of the design of the rosette, and it is believed that the device herein described completely overcomes this fault.

In the drawings, A is the upper half or base of a rosette, preferably made of porcelain and having holes a, a, through which pass the screws used for fastening it to a ceiling or, other support. Terminals 0, having a slot 6 and a screw 6 for holding and tapping an electric feed-wire, are held in appropriate re- 1' cesses in the porcelain by screwsc, said screws also serving to attach the U-shaped clips D. These clips, besides being used to hold thev lower half of the rosette to the upper half, also form electrical contact with the terminal f O and are made with projections d on their upper outside edges, which serve as stops.

B is the lower half or cap of the rosette, also formed of porcelain and having a hole E in the middle of its lower face. \Vithin it are four sets of terminals, in the present instance about ninety degrees apart. Two of the terminals are arranged opposite one an- Serial No. 33,736. (No model.)

pair of terminals I I are held in place by screws t', and have other screws q and p for the attachment of a fuse wire and connections leading out through the hole E, respectively.

In putting the two halves of the rosette together the part B is brought into contact with the part A and given a rotary motion. This causes the hooks F to engage the clips D, the rotation being stopped when the hooks F strike a projection d. The screws 77. are now set up and, striking the lower part of the clips D, clamp them firmly to the hooks F. This not only prevents the cap B from turning and becoming detached from the base A, but also insures good electrical contact between the terminals and the clips.

I claim as my invention 1. The combination in a rosette, of a base, a cap, means for coupling the cap to the base and one or more screws extending through the cap and bearing upon the said coupling means, substantially as described.

2. The combination in a rosette, of a base and a. cap, means for removably attaching the cap to the base by a rotary motion of the cap, and means operated from outside of the said rosette and applied to the means for holding the cap to the base, whereby the cap may be rigidly retained on the base after they have been removably connected, substantially as described.

3. The combination in a rosette of the character described, of a base, clips thereon,

. a cap for said base, hooks on said cap constructed to engage the clips on the base and a device operated from the outside of said rosette for clamping the hooks and clips together, substantially as described.

4:- The combination in a rosette, of a cap, hooks thereon, a base, a set of clips on the base, said hooks arranged to engage the clips whereby the cap may be detachably connected to the base, screws for clamping the clips to the hooks whereby the cap may be rigidly connected to the base, substantially as described.

5. The combination in a rosette of the character described, of a base-piece, a clip thereon, a cap, a terminal on said cap constructed to engage the clip on the base-piece, a tubular screw holding the terminal to the cap and a screw fitting the interior of said tubular screw and adapted to clamp the clip on the base to the terminal on the cap, substantially as described.

6. In a rosette of the character described, the combination of a base, electrical terminals on said base, U-shaped clips connected to said terminals, a cap, U-shaped hooks thereon, said hooks being held to the cap by the hollow screws, a second screw passing through each of the hollow screws and constructed to clamp the clips on the base to the hooks on the cap, a third screw on each hook of the cap, electrical terminals also on the cap and screws on said terminals, substantially as described.

7. The combination of a base, a cap constructed to fit on said base, clips on the base,
